Another limitation on this circuit is that the output resistance is defined by R1, which needs to be at least a few hundred ohms in order to limit the output of current in the op amp output. Some ADCs need to be
Referring now to FIG. 2, control over the comminution operation is maintained by a control circuit114shown schematically. The circuit114includes a microprocessor116, programmable controller, central processing unit or similar device, and is actuated by an actuator118, represented by a start switch loc...
